The Kennedy Half Dollar began production in 1964 after the death of President Kennedy. The 1964 Half Dollar was made with 90% silver. From 1965 to 1970 the silver half dollar production continued but with only a 40% silver content. From 1971 to present day the half dollar is made with a nickel/clad composition. In 2002 the U.S. Mint ceased production of the Kennedy Half Dollar for commerce use and started minting enough coins for collector demand only. The mintage levels dramatically dropped off as less than two million coins per year from each mint were made.
